Public bug reported:
SRU Justification
* Impact:
These devices can be found in some laptops. They don't work with the btusb in
bionic but still the btusb would be loaded.
* Fix:
There's a commit in upstream that makes btusb support these devices.

Bluetooth: btrtl: Add RTL8723D and RTL8821C devices
The Bluetooth parts of RTL8723D and RTL8723B share the same lmp
subversion, thus we need to check both lmp subversion and hci revision
to distinguish the two. The same situation is true for RTL8821A and
RTL8821C. Accordingly, the selection code is revised.
To improve maintainability, a new id_table struct is defined, and an
array of such structs is constructed. Adding a new device can thus be
as simple as adding another value to the table.

* Risk of Regression:
It's just one clean cherry-pick from upstream to extend devices supported by
btrtl. The potential risk should be low.
